middle of base, a wide, shallow basal depression towards each 

 s ; de ; punctures as on head. Elytra very little wider than 

 prothorax, but about four times as long, gradually narrowed 

 posteriorly, each with four irregular longitudinal costiform 

 elevations, connected by numerous irregular transverse or 

 oblique ones; with dense and rather coarse punctures, the 

 interspaces between same with small and not very dense punc- 

 tures, but becoming denser on the costse. Legs moderately long 

 and thin. Length, 21 mm. 



Hab. — Queensland: Kuranda (C. French). Type in 

 National Museum, Melbourne. 



In build fairly close to the male of cardwellensis, but 

 upper-surface with more conspicuous clothing, and elytra with 

 net-like elevations and much coarser punctures. On the male 

 of that species (on the female they are very different) there 

 are fairly dense punctures of moderate size, the largest being 

 distinctly less than half the width of the sutural interstice, 

 and all the interspaces are crowded with much smaller punc- 

 tures. On the present species the large punctures are at least 

 half of the width of the sutural interstice, many are quite as 

 wide, and a few are even wider; the interspaces are also much 

 less densely covered with small punctures. The elevated parts 

 are moderately clothed, but the depressed parts are almost 

 glabrous; whereas on the male of cardwellensis all parts of 

 the elytra are about equally clothed with short pubescence. 

 The first joint of the antennae is stout, rounded in front, 

 dilated to apex, and about as long as the distance between 

 the eyes; the second is short, with a short, subtriangular 

 inner projection; the third is about as long as the second, 

 but has a very long ramus (distinctly longer than the pro- 

 thorax is wide at the base) : the fourth to tenth slightly 

 diminish in thickness, but each has a ramus about equal to 

 that of the third; the eleventh joint is about as long as the 

 ramus of the tenth. 



A second specimen from Cairns (J. A. Anderson's No. 

 319) is smaller (16 mm.); its left antenna is broken, but 

 the right (fig. 8) is present and most peculiar. The fourth 

 and fifth joints are distinctly separated internally, but with 

 a long ramus common to both; the sixth and seventh and 

 eighth and ninth are similarly ramose. In other respects, 

 however, it agrees with the type.
